Description

58166-83-9 0UYY5V4U2Q Cafedrine [INN:BAN] 7-(2-(2-Hydroxy-1-methylphenethylamino)ethyl)theophylline Theophylline, 7-(2-(beta-hydroxy-alpha-methylphenethylamino)ethyl)- 5-26-14-00009 (Beilstein Handbook Reference) BRN 0583473 Cafedrina [INN-Spanish] Cafedrine Cafedrinum [INN-Latin] 7-(2-(beta-Hydroxy-alpha-methylphenethylamino)ethyl)theophylline Cafedrin 7-(2-((alphaS,betaR)-beta-Hydroxy-alpha-methylphenethylamino)ethyl)-1,3-dimethyl-2,6(1H,3H)purindion Cafedrina Cafedrinum UNII-0UYY5V4U2Q (-)-Cafedrine l-Cafedrine (CAS 58166-83-9) is a high-purity analytical reference standard with the molecular formula C18H23N5O3 and a molecular weight of 357.41 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 58166-83-9 0UYY5V4U2Q Cafedrine [INN:BAN] 7-(2-(2-Hydroxy-1-methylphenethylamino)ethyl)theophylline Theophylline, 7-(2-(beta-hydroxy-alpha-methylphenethylamino)ethyl)- 5-26-14-00009 (Beilstein Handbook Reference) BRN 0583473 Cafedrina [INN-Spanish] Cafedrine Cafedrinum [INN-Latin] 7-(2-(beta-Hydroxy-alpha-methylphenethylamino)ethyl)theophylline Cafedrin 7-(2-((alphaS,betaR)-beta-Hydroxy-alpha-methylphenethylamino)ethyl)-1,3-dimethyl-2,6(1H,3H)purindion Cafedrina Cafedrinum UNII-0UYY5V4U2Q (-)-Cafedrine l-Cafedrine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 58166-83-9 0UYY5V4U2Q Cafedrine [INN:BAN] 7-(2-(2-Hydroxy-1-methylphenethylamino)ethyl)theophylline Theophylline, 7-(2-(beta-hydroxy-alpha-methylphenethylamino)ethyl)- 5-26-14-00009 (Beilstein Handbook Reference) BRN 0583473 Cafedrina [INN-Spanish] Cafedrine Cafedrinum [INN-Latin] 7-(2-(beta-Hydroxy-alpha-methylphenethylamino)ethyl)theophylline Cafedrin 7-(2-((alphaS,betaR)-beta-Hydroxy-alpha-methylphenethylamino)ethyl)-1,3-dimethyl-2,6(1H,3H)purindion Cafedrina Cafedrinum UNII-0UYY5V4U2Q (-)-Cafedrine l-Cafedrine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
